Do all training courses for building technicians CHE (formerly building technicians CHE) take the same amount of time?

There are very different training courses in the field of building technology. For example, you can attend one-day courses to become a building services technician or complete a diploma course at a College of Higher Education to become a building services technician CHE (formerly technician CHE building services), which at some schools takes up to 7.5 semesters while working. For example, the diploma course in building services engineering at one College of Higher Education can be completed in 6 semesters while working, at another full-time in 6 semesters. The schools will inform you directly about the exact duration of the course.
